SIP Panel U-Values Guide

Below is a selection of U-Value calculations for different thicknesses of Sips Eco Panels used in roof and wall constructions.

NB – because the SIP panel provides the bulk of the insulation, altering the roofing finish does not drastically affect the U-Value.  All dimensions are nominal and within a tolerance of +/-3mm

Calculate your SIPs Roof & Wall U Value

Wall Type 1 = 102.5mm brick, 60mm cavity, breathable reflective membrane, SIP wall panel at specified thickness, vapour membrane, 25mm service batten, 12.5mm plasterboard, 3mm skim 

Wall Type 2 = 5mm render, 12mm MGO panel exterior, breathable membrane, SIP wall panel at specified thickness, 25mm service battens, 12.5mm vapour check plasterboard, 3mm skim. 

Wall Type 3 = 18mm Timber cladding, 50mm ventilated cavity, reflective breathable membrane, SIP wall panel at specified thickness, 25mm service batten, 12.5mm vapour check plasterboard, 3mm skim. 

Roof Type 1 = Standard clay tiles, 25mm tiling batten, 25mm counter batten, breathable roofing membrane, SIP roof panel at specified thickness, 25mm service void, vapour check plasterboard, 3mm skim. 

Roof Type 2 = Standard clay tiles, 25mm tiling batten, 25mm counter batten, breathable roofing membrane, SIP roof panel at specified thickness, 25mm service void, 50mm Thermaline super, 3mm skim.
